Topic: How to block a specific email address

I am looking for some assistance on blocking a particular email address. This person is harassing one of my users, but since it is a gmail account I do not want to block the whole domain, just the specific email address.

Re: How to block a specific email address

user@gmail.com  REJECT Sorry, you're not welcome here.
or
user@gmail.com DISCARD

Discard one doesn't give a notification, takes the mail in and gets rid of it after that. Whereas Reject sends the mail back by not even accepting.

Put it under /etc/postfix/sender_access.pcre
The file is already in the config so just restarting postfix will do.

Thank you.

I did see the file under postfix, but was unsure of the file structure. Do I not have to hash this file?

Nope, just save it.

Re: How to block a specific email address

Another way is storing the blacklist in SQL database. Try this:

cd /opt/iredapd/tools/
python wblist_admin.py --add --blacklist 'user@domain.com'

Zhang,

Does it apply to all backends? Or just for MySQL backend?

Editing the .pcre file is easy and if you're not in for blocking thousands,  easier to manage. Also works with any backend and you can move the files to other setups easily as well.

It works for all backends supported by iRedMail.
